GRILLED CHOCOLATE ANGEL FOOD CAKE

Steps:

• Preheat the oven to 350 degrees F.
• Sift the flour, cocoa powder, baking soda, espresso powder, salt and 3/4 cup sugar into a large bowl. Whisk in the chocolate and set aside.
• Add the egg whites and cream of tartar to the bowl of a stand mixer fitted with the whisk attachment. Whip the whites on medium-high speed until foamy, about 30 seconds. Slowly pour in the remaining 3/4 cup sugar and whip on high speed until the whites are glossy and can hold a stiff peak. Add the vanilla and beat to combine. Remove the bowl from the mixer.
• Gradually add the flour mixture, gently folding it into the egg white mixture, until fully combined. Spoon the batter into an ungreased 10-inch tube pan and bake until the cake springs back when pressed with a finger, 30 to 35 minutes. Do not open the oven during this time. Let cool, inverted, for 1 hour before removing the cake from the pan.
• To grill the cake: Preheat an outdoor grill or grill pan over medium-high heat. Slice the cake and brush both sides of each slice lightly with the butter. Grill the cake slices until the surface becomes lightly caramelized and grill marked, about 1 minute per side. Serve with the berries, a dollop of whipped cream and a sprinkling of grated chocolate.
